Feds: $1.7 million of Chinese fentanyl seized at Philly port

110 lbs (50 kilograms) of fentanyl seized from Chinese shipment at Area Port of Philadelphia on Monday, June 25, 2018.

Federal authorities intercepted nearly $1.7 million worth of fentanyl at the Area Port of Philadelphia last week, marking another seizure in an aggressive push to take the deadly synthetic opioid off the streets.

Customs & Border Protection officials said 110 pounds of the drug were found during a routine examination of a shipment of iron oxide that had arrived from China.

A narcotics detector dog tipped off CBP agents to the suspicious cargo, prompting an inspection of the package using protective gear. Authorities discovered 50 packages containing sealed bags of a white, powdery substance.

"Opioids, including fentanyl and its analogues, are a serious public health concern, and the importation of vast amounts of this deadly synthetic chemical compound is a national security threat," said Casey Durst, director of field operations in Baltimore for CBP.

Fentanyl seizures by CBP have been on the rise over the past three years, jumping from 440 pounds nationally in 2016 to 951 pounds in 2017 and 984 pounds as of the end of April 2018.
